vrad fails to run, fails with error "OS error message: Access is denied"

[candid mica]

This seems to be a fairly common occurence according to google where the tips are usually reinstall or to launch hammer as admin, something I don't fully understand how to do since hammer now seems to be launched via the cs2 executable. I have made sure to elevate privileges for all users for both cs2.exe and vrad3.exe, but I am unsure if that's where the access problem even comes from. I had a look at what cli command is actually ran and noticed that it was trying to write to appdata/temp/ on the c: drive instead of d: where cs is installed, so I figured i would run it manually and target a temp drive on d: but the same error persists. If someone has any idea as to what folders/files vrad is trying to modify that would be awesome!

Thanks!
